Actually, Tanaga didn't lie on the 'regaining memory' part. While he was walking towards the elevator, pieces of his memory were flashing back. That's why he was walking fast, afraid of passing out in the middle of carrying his wife.
Ashley had no choice but to put her arms on her husband's neck and rest her head on his chest. She clearly heard Tanaga's heart racing as much as her heart was doing.
When they arrived at the third floor, Tanaga was heading straight to the bathroom when Ashley stopped him.
"Tan wait! Put me down on the sofa, please?" Ashley asked softly while she couldn't look straight at Tanaga's eyes.
Tanaga paused and stared at his wife whose head was buried in his chest. "Oh? You don't need to use the restroom now?" Ashley shook her head and didn't speak.
Instead, Tanaga went to the bed and carefully put her down there. Then he placed the pillows properly and helped Ashley to lie down.
